Overview of Web Application Development 

Are you planning to or working on developing a web application? If yes, this blog is for you. This blog covers everything. From understanding what is a web application to its types and the development process to its benefits. So, let’s start with an overview of web application development. 

What is a Web Application?

A few years ago, web pages were still and lifeless. But now, gone are the days of basic web pages with just images and videos scattered around. You can now make visually appealing web applications much more easily and quickly. 

A web application is often called a web app. It is a computer program that uses a web browser to perform an action. It comprises a client side and a server-side. Therefore, the user enters data through the front end while the back end of the application stores and processes the information. Some common examples of web applications are shopping carts, content management systems, and online forms.

Note that both individuals and enterprises build web applications for different purposes. Web apps help incorporate tailored user experience of native applications. Also, it is easy to access from a web browser on any device. For instance, Facebook, Linkedin, and Mailchimp have web applications that offer tailored user experiences of native apps. Hence, web application development is gaining popularity these days. Some highly preferred web app development industries are banking, eCommerce, healthcare, education, etc. 

What is Web Application Development?

Web application development is creating an application that runs on a web server. It interacts with a browser. Also, the process of developing a web application is usually aided by a web application framework. 

How does a Web Application Work?

You can access a web application over a network. Also, unlike a mobile app, you don’t need to download it. Instead, you can easily access it through a web browser. It could be Google, Yahoo, Opera, or Safari. 

Usually, a web application comprises three components:

  • A Web Server – manages requests from the client
  • An Application Server – processes requests
  • A Database – stores the information.

Here’s an overview of a typical web app workflow: 

  • A user triggers a request to the web server. It could be through a web browser or the application’s user interface. But, all of it happens over the internet.
  • Web server receives the request from the browser.
  • Next, the web server instructs the appropriate web application server to process the request.
  • The application server performs the triggered task and generates the result.
  • Last, the web server displays the requested information on the screen.

Moreover, web apps are generally coded using the following:

For the front end development:

  • HTML5
  • Java Script
  • CSS

For back end development:

  • PHP
  • Java
  • Ruby

Types of Web Applications

Now that you’ve gone through the overview of a web application, let’s get to the different categories. Usually, there are 6 significant types of web applications. You can classify them based on their functionalities, tools, and technologies. 

1. Static Web Apps

A static web app does not involve interaction between the server and the user. It features per-rendered cached content. Also, it goes to the user’s browser with minimal or no interactivity. Moreover, there is no interaction either. If any changes take place on the page, it is generally after loading. A company’s website and a person’s portfolio websites are good examples of Static Web Apps.

2. Single Page Applications

This type of web application does not involve any hindrances at pace. You can smoothly continuously interact with the single page interaction. What’s best is that it dynamically rewrites the current page instead of loading entire new pages from a server. Here, SPAs perform logic browser and not on the server. As a result, user requests and responses occur effectively. Also, faster than conventional web applications. Some of the prominent single-page applications are Netflix, Twitter, Google Maps, etc. 

3. eCommerce Web Application

Well, who’s not familiar with this? An ecommerce web application is an online shop. It promotes buying or selling anything online. Hence, this application requires certain major features like

  • Electronic payment integration
  • Transaction integration
  • An effective management panel for administrators (listing/updating/deleting Products and managing orders/payments)
  • A personal cabinet for users.

Furthermore, eCommerce apps are centered around technologies like

  • Electronic payment gateways
  • Supply chain
  • Inventory management systems 
  • Mobile commerce 
  • Supply chain management
  • The internet market

Some of the famous examples of eCommerce web apps are Amazon, Swiggy, Zomato, etc. 

4. Dynamic Web Application

A dynamic web application engages the users with the help of certain elements and generates real-time data. It generates code in real time. That makes it possible for the page display to change each time a page is refreshed or new input is added. Hence, this kind of application requires a database to store data. Moreover, as fun, as they may sound, they’re more complicated on a technical level. You need to use many programming languages for a dynamic web application. The most common ones are PHP and ASP.NET. Furthermore, a great example of a dynamic web application is Facebook. Here you can log in easily and communicate with your friends and family without hassle.

5. CMS Web Apps

Using a CMS web app, you can create your own content. Also, you need not have any technical knowledge. You learn as you use it. Consequently, a CMS allows for website development focusing entirely on the UI and not the code. CMS is famous for its use in writing and managing blogs, media sources, etc. A few popular CMSs are WordPress, Drupal, Jhumla, etc. 

6. Progressive Web Apps

Now, out of all the others, progressive web apps are the most popular type of web app. Moreover, these are the most well-developed types of web applications. Hence, they look pretty similar to mobile apps. A progressive web app is also known as a cross-platform web app. Why? Because it uses the latest browser APIs and progressive enhancement methods to provide users with a native mobile application experience. In addition, the primary goal of a WPA is to boost the speed and versatility of web applications when there is a slow internet connection. 

Web App vs. Websites 

Now that you’ve covered all the basics and the types of web apps, let’s understand the difference between web application vs website. 

Web applications are websites indeed. Users can access both on a web browser. Also, both require access to the internet. At first, it may seem like there is no difference between the two. But, today, the lines between a web app and a website are blurred. The following table will give you an overview of Web App vs. Websites.

Web AppWebsite
It is Dynamic and encourages user engagement.Only contains static content.
It is interactive and responds to the user’s input. One-way informational feed. It does not allow user interaction. 
Requires authenticationSince it’s an informative site, authentication is not mandatory. 
Has got higher and complex functions.Has got relatively simple procedures.
It requires recompilation before deployment. It need not be pre-compiled.
Integration with other software is complicated.Third-party application integration is hassle-free. 

Web App vs. Mobile Apps

Now, web apps and mobile apps are similar in many ways. Yet, they differ at various marks. Let’s look at the significant differences between web apps vs mobile apps.

Web AppsMobile Apps
You can access them on any gadget.Firstly, mobile apps are made only for mobile devices.
They run on a server, which you can use on a web browser. They’re suitable for android, IOS, and cross-platform operating systems.
